Berghia Nudibranchs

[monocus]

you will never really get rid of aptasia .i had rock 6 months out of water and they still came back.i have one berghia right now and will be bringing more in next year-probably feb-march.aptasia is actually good in the sump as they help clean the water,and if your copperband is keeping the display clean , i wouldn't worry too much about it right now
